A.both traffic shaping and traffic policing cause retransmissions of connection-oriented protocols such as TCP
B.both traffic shaping and traffic policing support the marking and re-marking of traffic
C.the effects of traffic shaping and traffic policing when configured on a router are applied to outgoing traffic
D.traffic shaping queues excess traffic whereas traffic policing discards excess traffic
E.traffic shaping allows the traffic to exceed the bit rate whereas traffic policing prevents the traffic from exceeding the bit rate
